How to write the explicit formula of a geometric sequence given two terms of

The video tutorial covers the use of explicit formulas in sequences, focusing on substituting variables and determining the ratio R. The teacher explains how to correctly calculate the ratio by addressing common errors, such as incorrect subtraction instead of division. Once the ratio is determined, it is applied to find the first term in the sequence. The lesson concludes with some casual remarks.

What happens when you plug in a different number for N in the explicit formula?

How do you determine the value of R using the given values?

What is the process to find the square root of R squared?

What is the significance of choosing the smallest numbers when determining values?

Explain how to find A sub 1 based on the given information.
